Default BROWN Horn Speaker repair

Please, is there a Brown's Horn Speaker expert out there ? (See my Horn Speakers thread in "Components & Circuits").
The Magnet/Coils/Diaphragm assembly is the most complicated I've ever seen. Bog standard EM mikes, earphones/speakers - yes, but horn speaker technology - never seen one(or4) till Sunday. Sadly, moisture has penetrated in the last 90 years, & some rust & corrosion built up, but not beyond removal. One coil reads 930 ohms & the other is o/c.
Me thinks that it would be prudent to get an expert to repair it. I'll manage the big round hardwood base, the big brass mounting ring, and the spun ally horn(with its willy shaped inner end). The number B 50337 has been stamped on the wooden base & bottom wooden disc.
Can anyone help ?

Regards, David
